area. other than those at isolated storms, it will be mostly clear for most people tonight. tomorrow, there is a better chance for thunderstorm activity as a stronger cold front comes through. this separate summer from fall. 80's as you get towards to cleveland. that cool fall air will be pushing through, but the front itself will likely turn into thunderstorms. we will wake up to a partly cloudy sky, maybe some patchy fog. i think we will also get a little front early on. when the front comes in, we will have a line of thunderstorms reaching the inner harbor and the western shore of the bair around 5:00, 5:30 -- the bay area around 5:00, 5:30. a sprinkel may linger in the mountains, but we will see clearer skies.
